Basically everything that works with Arduino works with NEXTuino. Use the development environment you already know — or explore new ones. The choice is yours.
The official open-source development environment for Arduino — and the most direct way to program any NEXTuino controller. Install the NEXTuino board package in seconds and you are ready to go. Every Arduino sketch, every library, every example runs without modification.
#include <NEXTuino.h>
// Runs once on power-up
void setup() {
NEXTuino.begin();
Serial.begin(115200);
}
// Main control loop
void loop() {
bool sensor = NEXTuino.readDI(1); // Digital input 1
NEXTuino.writeDO(1, sensor); // Mirror → relay out 1
float level = NEXTuino.readAI(2); // Analog 0–10 V
if (level > 8.5) {
NEXTuino.writeDO(2, HIGH); // Trigger alarm relay
}
Modbus.send(0x01, level); // RS-485 Modbus RTU
delay(100);
}From visual drag-and-drop environments to professional engineering platforms — NEXTuino works with the tools that best fit your workflow.
A professional embedded development platform built on top of Visual Studio Code. PlatformIO brings dependency management, build system automation, unit testing, and advanced debugging to NEXTuino projects — a significant step up from the standard IDE for complex applications and team workflows.
Learn more ↗The first open-source IEC 61131-3 compliant PLC runtime. Program NEXTuino using standard industrial languages — Ladder Diagram, Function Block Diagram, Structured Text, Instruction List, and Sequential Function Chart. OpenPLC also includes a web-based HMI builder, making it ideal for engineers transitioning from traditional PLC platforms to open hardware.
Learn more ↗The power of VS Code's IntelliSense, integrated debugging, and Git workflow combined with the Visual Micro extension for full Arduino compatibility. A natural choice for developers who spend most of their time in VS Code and want a professional environment for NEXTuino firmware development.
Learn more ↗A visual drag-and-drop programming environment for Arduino-compatible hardware. Build complex control logic by connecting functional blocks — without writing a single line of code. Visuino is well suited for rapid prototyping, educational use, and applications where visual logic design is preferred over text-based programming.
Learn more ↗Model-based design, signal processing, and control system development with direct hardware deployment via MATLAB Simulink and the Arduino support package. Ideal for control engineers prototyping PID loops, filter designs, or state machines in MATLAB and deploying them to NEXTuino hardware without manual code translation.
Learn more ↗Open-source scientific computing largely compatible with MATLAB. Connect NEXTuino to Octave for data acquisition, real-time sensor monitoring, and control algorithm prototyping — without a commercial license. A practical choice for research and academic environments running Arduino-connected test benches.
Learn more ↗A graphical programming environment that generates optimised embedded code from flowchart-based designs. Flowcode's visual approach bridges the gap between system-level logic design and embedded implementation — useful for teams where control logic is designed by engineers who are not primarily embedded programmers.
